Mellanox MT25408 on proxmox 5.x

[peril]

In attempting to get older Infinband cards as ethernet devices in proxmox 5, I'm able to see the cards up with lspci -k, but don't see any devices being created in dev which would give a hook for any of the management toolsets to connect to the cards (setting port types, firmware flashes, etc.)

below are the pci devices; looking for some clue for udev rules to get this plumbed in as ethernet interface and how to troubleshoot - the mellanox support site being rehosted has made it difficult to research as the original sites on force.com are not returning content from google searches.

Happy for any recommendations / help (or discouragement if this is too old / persnickety of a setup). If anyone has these setup with proxmox4 or 5 would love to hear about your setup and config.

Hi,

ensure you have set this card in Ethernet mode.

to change the mode you have to install the Mellanox tools for it.
